Description

Computer

The NMS 8250 is a professional computer made by Sanyo for the Dutch company Philips. The machine itself is basically the MPC-25FD rebranded and localised for the European market. The abbreviation NMS stands for New Media Systems.

The computer is a desktop model with a modern and business-like design and features one built-in disk station. The color is dark silver and gray. A location is planned for the addition of a second disk drive.

The NMS 8250 is almost identical to the Philips NMS 8255, with the only real difference being the number of disk drives. The NMS 8250 has one, while the NMS 8255 has two. For both models the label on the front will say NMS 8250. To see the actual model, you need to check the label on the back of the machine.

The NMS 8250 is also very similar in appearance to the NMS 8280.

This computer comes with 128kB RAM (not 256kB as indicated on the machine and the box by adding the VRAM). Three models were produced:

  • NMS 8250/00 for the Dutch and Belgian markets, keyboard layout is QWERTY
  • NMS 8250/16 for the Spanish market, keyboard layout is QWERTY with ñ key
  • NMS 8250/19 for the French and Belgian markets, keyboard layout is AZERTY

Belgium is a country with 3 official languages: Dutch - French - German. With exception for the NMS 8220 and the NMS 8280 only available in the Dutch version, also in the French speaking part (Wallonia), all the Philips MSX computers released in Belgium were different according it was in Flanders (Dutch) or in Wallonia (French).

Specifications

The NMS 8250 is an MSX2 with a Z80A from NEC (D780C-1) and an MSX-Engine S3527 from Yamaha.

This model is known for SCC (and other sound cards) mixing issues. There are several modifications fixing this, the opamp mod by Daemos and luppie not being the worst one.

The plastic front panel also gets very fragile with age. Special care must be taken when shipping that absolutely no stress is placed on the front panel.
